Every year, ovarian cancer kills approximately 14,000 women in the United States and more than 140,000 women worldwide. Most of these deaths are caused by tumors of the serous histological type, which is rarely diagnosed before it has disseminated. By deep paired-end sequencing of mRNA from serous ovarian cancers, followed by deep sequencing of the corresponding genomic region, we identified a ...

Urate oxidase (UOxase; urate:oxygen oxidoreductase, EC 1.7.3.3), which catalyzes the oxidation of uric acid to allantoin, is present in most mammals but is absent in humans and certain primates. A cDNA clone for UOxase containing an insert of 1.3 kilobases (kb) was isolated from a lambda gt11 cDNA library prepared from rat liver mRNA. This recombinant clone with a 1283-nucleotide insert has seq...

Skeletal muscle satellite cells in their niche are quiescent and upon muscle injury, exit quiescence, proliferate to repair muscle tissue, and self-renew to replenish the satellite cell population. To understand the mechanisms involved in maintaining satellite cell quiescence, we identified gene transcripts that were differentially expressed during satellite cell activation following muscle inj...

As an approach to the study of yeast pre-mRNA splicing in vivo, we have examined properties of transcripts derived from a gal-UAS intron-containing fusion gene encoding RP51A and a series of its derivatives. RNA half-life measurements were carried out after transcription initiation was blocked by the addition of glucose. Pre-mRNA encoded by GalRP51A decayed with a half-life of approximately 6 m...

The MITF/TFE subfamily of basic helix-loop-helix leucine-zipper (bHLH-LZ) transcription factors consists of four closely related members, TFE3, TFEB, TFEC and MITF, which can form both homo- and heterodimers. Previously, we demonstrated that in t(X;1)(p11;q21)-positive renal cell carcinomas (RCCs), the TFE3 gene on the X chromosome is disrupted and fused to the PRCC gene on chromosome 1. Here w...

breast carcinoma is the major cause of cancer-related death in women. the incidence of this carcinoma is rising and there are many attempts to decrease this problem. the aim of this study was detection of full-length cytokeratin 19 (ck19) mrna, in peripheral blood and tissue of breast cancer patients in early stage of cancer. in this study, rt-pcr (reverse transcriptase-polymerase chain reactio...

SnowShoes-FTD, developed for fusion transcript detection in paired-end mRNA-Seq data, employs multiple steps of false positive filtering to nominate fusion transcripts with near 100% confidence. Unique features include: (i) identification of multiple fusion isoforms from two gene partners; (ii) prediction of genomic rearrangements; (iii) identification of exon fusion boundaries; (iv) generation...

Background: Hyper-androgenemia is one of the main clinical features of polycystic ovarian syndrome (PCOS). Letrozol is an aromatase inhibitor drug, which is co-administered with gonadotropins in most cases of PCOS, to improve ovulation. Aromatase has a critical role in catalyzing the conversion of androgens to estrogens and is responsible for keeping the homeostatic balance between them. Hence ...

Objective Orexin is a hypothalamic orexigenic neuropeptide, which third cerebral injection of it mainly exerts inhibitory effects on reproductive functions. It increases significantly the Aromatase (Cyp19) gene expression in the hypothalamus of male rats. Aromatase is an enzyme which converts androgens to estradiol in the hypothalamus of rats. Prenatal or neonatal exposure of females to testost...
